Notes
How detection works
Detection uses an ordered table of regular expressions, checking the most specific browser signatures (Edge, Opera, Samsung Internet) before falling back to Chrome, Firefox, Safari, or Internet Explorer. Results are heuristic — user agents can be spoofed or incomplete.
About the User Agent Parser
Paste a raw User-Agent header to identify the browser and version, rendering engine, operating system, and device type using a compact table of regular expressions. Includes a one-click button to load your own browser's UA.
